THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 700,195, dated May 20, 1902.

, Application filed January 22, 1902. Serial No- 90,855- (No model.) I

T0 at whom, it may concern:

Be it known that we, MATHIAS L. HEGG- LUND and WILLIAM W. REVELL, citizens of the United States, residing at'Pierre, in the county of Hughes and State of South Dakota, have invented certain new and' useful Improvements in Thill-Oouplings; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and, use the same. I V

This invention relates to thin-couplings, and more particularly to that class in which the shafts may be easily and quickly attached or detached.

The object of the invention is to provide a thill-coupling having means for locking the conpling-bolt in such a manner that all possibility of its becoming loose or dropping out is avoided.

Another object is to provide a thill-coupling with means for locking the bolt in such a manner that it may be easily and quickly withdrawn and replaced and one which is exceedingly cheap and simple in its construction and will efficiently perform all its intended functions;

With these objects in View and such others as may hereinafter appear our invention consists in the particular construction of the various parts and in the novel manner of combination and arrangement of said parts, all of which will be more fully described, and specifically pointed out in the appended claims.

In the drawings forming a part of this specification, Figure 1 is a perspective view of our invention complete. Fig. 2 is a side elevation of the same. Fig. 3 is a modification.

Referring by letters to thedrawingsgA represents a clip having the usual ears B,-provided with oppositely-disposed aperturesQ and D represents the thill, which is provided upon its free end with the usual aperture E, adapted to register .withthe apertures in the ears and to receive the coupling bolt or pin F.

Secured to the clip or formed as a part thereof is a flat plate or arm G, which is adapted to lie fiat against the axle. This arm is provided with a flat spring H, the free end of which engages an angular rocking arm I, pivoted to the flat plate or arm Gr; One side of l the angular arm rests upon the ears andthe other is bent at right angles to the respective sides in such a position as to engage the head of the belt or pin and prevent the same from working loose or falling out, the spring serving toretain the arm in a closed position.

In Fig. 3 we have shown a modified form of our invention, which consists of forming the angular rocking arm, or that portion which rests upon the ears of the clip, in the projection J, which is bent back upon itself so as to form an antirattler.

We deem the foregoing explanation sufficiently plain that the invention will be readily understood by all conversant in such matters, the extreme simplicity rendering an elaborate description unnecessary.

WVe claim 1. In a thill-coupling, a clip formed witha projecting arm, a spring-actuated angular rocking arm pivoted to the first-mentioned arm, one side of the angular rocking arm engaging the ears upon the clip, the other being bent at right angles to therespective sides parallel with the ears, substantially as shown and described.'

2. In a thill-ooupling, a clip formed with a plate projecting at one side thereof, an angular rocking arm pivoted to the said plate, a

spring secured to the plate, the said spring engagingthe said rocking arm,-one side of the angular arm engaging the ears upon the clip, the other being bent at right angles to the respective sides of the arm parallel with the ears,substantially as shown and described.

In a thill-coupling, a clip having a flat projecting arm, a spring-actuated angular arm pivoted to the said flat arm, one side of the angular arm] being bent at right angles to the respective sides, the other resting upon the ears, and of an antirattler formed upon that portion which rests upon the ears, substantially as shown and-for the purpose set forth.

In testimony whereof we affix our signa tures in presence of two witnesses.
